Veritas Storage Foundation 5.1 SP1 Cluster File System Administrator"s Guide (5900-1738, April 2011)

Point agent continues monitoring the old set of coordination points it read from
vxfenconfig -l output in every monitor cycle.
The status of the Coordination Point agent (either ONLINE or FAULTED) depends
upon the accessibility of the coordination points, the registrations on these
coordination points, and the fault tolerance value.
When the changes to vxfenmode file are committed and reflected in the
vxfenconfig -l output, then the Coordination Point agent reads the new set of
coordination points and proceeds to monitor them in its new monitor cycle.
Troubleshooting server-based I/O fencing in mixed mode
Use the following procedure to troubleshoot a mixed I/O fencing configuration
(configuration which uses both coordinator disks and CP server for I/O fencing).
This procedure uses the following commands to obtain I/O fencing information:
■ To obtain I/O fencing cluster information on the coordinator disks, run the
following command on one of the cluster nodes:
# vxfenadm -s diskname
Any keys other than the valid keys used by the cluster nodes that appear in
the command output are spurious keys.
■ To obtain I/O fencing cluster information on the CP server, run the following
command on one of the cluster nodes:
# cpsadm -s cp_server -a list_membership -c cluster_name
where cp server is the virtual IP address or virtual hostname on which the CP
server is listening, and cluster name is the VCS name for the SFCFS cluster.
Nodes which are not in GAB membership, but registered with CP server indicate
a pre-existing network partition.
Note that when running this command on the SFCFS cluster nodes, you need
to first export the CPS_USERNAME and CPS_DOMAINTYPE variables.
The CPS_USERNAME value is the user name which is added for this node on
the CP server.
■ To obtain the user name, run the following command on the CP server:
# cpsadm -s cp_server -a list_users
where cp server is the virtual IP address or virtual hostname on which the CP
server is listening.
The CPS_DOMAINTYPE value is vx.
The following are export variable command examples:
